VALVE.

Specification of Letters Patent.

Patented Jan. 23, 1912.

Application filed February 24, 1910. Serial No. 545,591.

To all whom it may concern:

Be it known that I, THOMAS P MOsELEY, a citizen of the United States,and residing at Vallejo, in the county of Solano, State of California,have invented certain new and useful Improvements in Valves; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to improvements in valves and more especially toinlet valves for use in connection with water closet flush tanks usuallyemployed in the water systems of dwelling houses, theaters, hotels andother buildings.

It has for its object to prevent the noise caused by thesplashing ofwater as it enters the flush tank, to regulate the height of the waterin the tank and the length of the float lever and to control theoperation of the inlet valve.

It also has for its object to provide. an inlet valve. for water closetflush tanks which is simple, inexpensive and durable in construction,not liable to get out of order, and exceedingly easy in operation.

It still further has for its object to provide a combined) inlet valveand overflow pipe.

The device consists in the several features and combination of featuresas hereinafter more fully described and claimed.

lefer'ring to the drawings :-Figure 1 is a vertical section through theflushing tank with the inlet valve and float in elevation.

Fig. 2 is an enlarged vertical section of the inlet valve and float.Fig. 3 is a top plan view of the same. Fig. 4 is a bottom plan view ofthe float. Fig. 5 a horizontal section on the line 1?m of Fig. 2. Fig. 6a detail section of the valve plug.

In the drawings in which like numerals of reference denote like partsthroughout the several views, 1 represents a flush tank of the usualtype now in common use, but which may be of any other desired form, sizeor construction and may be. made of any desired material. In the bottomof the flush tank an opening 2 is provided in which the water inletvalve 3 is mounted. The water inlet valve comprises a casing or pipe 4with its extreme lower port-ion 5 screwthreaded and an annular flange 6at the upper extremity of the screwthreaded portion and an upper portion7 preferably smaller in circumference than the lower portion 5.

A nut 8 is provided for retaining the casin or pipe 4 in the opening 2of the flush tan and a washer or gasket 9 is placed between the flange 6and the bottom of the flush tank to insure a water tight joint. Justabove the flange 6 the casing or pipe 4 is provided with a doublerow ofwater outlet holes 10.

11 is a stationary mufller comprising a. cylinder 12 having its bottommounted on the lower portion of the casing or pipe 4 and its top on theupper portion 7 of the same, said cylinder being provided with a seriesof water outlet holes 13 in the bottom. The upper end of, the upperportion 7 of the casing or ipe 4 is beveled as at 14, and 15 is avertlcally slidable mufiier mounted thereon which comprises, acap 16having a vertical bore 17 therethrough screwthreaded at the top, abeveled annular portion 18, corresponding in shape to the beveledportion 14 of the casing or pipe 4 on which it is designed to be seated,and a series of holes 19 in the top thereof..

Inside the casing or pipe 4 a partition 20 is provided, below ,theoutlet holes 10, having a central aperture 21, said partition forming aseat for the vertically slidable valve p a asa iralv irlu being p videdwit-h longitudinally eitiiending ribs' 23, on its exterior, for the purose of forming spaces 24 betweenit and t e inner surface of the casingor pipe 4 for the passage,

of water from the inlet pipe to the interior of the flushtank. The valveplug 22' is proavided'with a valve stem 25 which is inside i the casingor pi 4, the lower end of which is screwthreade and screwed into thesame, 26 and 27 being washers secured on said valve stem inside theupper and lower portions of the valve plug, respectively, and 28 is anut for securing the valve plug on said stem. The upper end of the valvestem 25 is provided with screwthreads 29 with which the screwthreads inthe top of the vertically slidable mother 15 engage and 30 is a thumbnut on the extreme upper end of the valve stem. The extent of movementofthe valve plug 22, in relation to its seat, which governs the amount ofwater entering the flush tank and the space between the muffler 15 andits seat, which governs the amount of water flowing out of the bottom ofthe same, are. both regulated by the adjustment of said mufiier15 on thescrewthe lever has been adjusted to the length that will maintain therequisite pressure on the valve plug 22, 38 being a slot in the part 35of the float lever through which the valve stem 25 passes. The part 36of the float lever 33 is provided witha weight 39 which is adjustablethereon and adapted to be held at any desired'point by means of a thumbscrew 40. To the outer end of the part 36 of the float lever 33 a band41 is pivoted by means of a thumb nut 42, leather washers 43 beingprovided between the ends of'the band and the part 36 of the floatlever.

44 is a float which is encircled bythe band 41- and on which said bandis designed to be adjusted and fixed at any desired point for thepurpose of regulating the height of water in the flush tank. The floatcomprises a hollow inverted cup shaped cylinder 45 having a concaveflange 46 extending upwardly and inwardly from the lower edge thereofforming a central opening 47.

The upper part of the cup sha ed cylinder 45 being air tight the concaveange assists in the opening "of the valve by causing a downward suctionas the wateris drawi from the tank:

57 is a flush valve connected to a cord or chain which is operated bymeans of a reel or wheel 67 which in turn is designed to be operated bymeans of a crank 68.

The operation is as follows :'Assuming that the flush tank contains theusual supply of water, by turning the crank 68 to the right the wheel orreel 67 is caused to rotate and winds the cord or chain thereon whichcauses said cord orchain to elevate the flush I valve 57 and permitswater to escape from the flush tank. As the water escapes its level inthe flush tank will gradually become lower and lower and this togetherwiththe downward suction-of the water on the float assists in thedownwardimovement of the float, and the downward movement of the floatcauses the valve plug 22 to move downward which allows water from theinlet pipe to pass into the casing or pipe 4, through the holes 10 intothe stationary mufller 11 and through the holes 13 in the bottom thereofinto the flush tank. The mufiler' 11 directs the water gently downwardthrough the holes 13 and distributes it without any spraying, splashingor noise. Any water that passes the holes 13 and flows upward throughthe portion 7 of the casing or pipe 4 will enter the vertically slidablemuffler 15 and will be directed downward thereby without any spray,splashing or noise. By constructing the float 44 with a concave flangeat the bottom and a central opening, when the flush tank is filling, theair imprisoned in the float will keep the water line in the float belowthe water line of the flush tank and this displacement will tend toprevent the float from rising as fast as it would otherwise, that is tosay it becomes automatically heavier, on account of the water therein,than a closed float of the same dimensions and still floats. Theadvantage of this added weight becomes apparent when the water isallowed to run out of the flush tank, for then the water line in thefloat will be above the water line in the tank and cause the float toact as a weight to draw down the outer end of the lever 33 and opens theinlet valve.

I do not desire to be understood as limiting myself to the specificdetails of construction' and arrangement as herein described andillustrated, as it is manifest that variations and modifications may bemade in the features of construction and arrangement, in the adaptationof the device to the various conditions of use without departing fromthe spirit and scope of my invention and improvements. I thereforereserve the right to all such variations and modifications as properlyfall within the scope of my invention and the terms of the followingclaims.
